Ivanka Trump called to cooperate with investigation into January 6 insurrection and her father's role

Ivanka Trump, the daughter of former President Donald Trump, has been asked to cooperate with an investigation by US lawmakers into the January 6 insurrection, following claims that she implored her father to call off the violent mob which broke into the Capitol building.

The House committee investigating the riot has sent a letter requesting a meeting with Ms Trump, who was an adviser to the former President, and was in direct contact with her father as some of his supporters stormed the Capitol in an effort to halt certification of Joe Biden's presidential win.

The panel cited testimony that Ms Trump implored her father to quell the violence and said it wants to ask about her actions while the insurrection was underway.

The committee also says it wants to discuss what Ms Trump knew about her father's efforts to pressure then-Vice President Mike Pence to reject the 2020 election results - including a telephone call they say she witnessed.

During the call, it has been claimed that Mr Trump questioned whether Mr Pence had the courage to delay the counting of the votes.

A statement released by Ivanka Trump's spokesperson did not address whether she would cooperate with the committee's investigation.

"Ivanka Trump just learned that the January 6 Committee issued a public letter asking her to appear," a statement said. "As the Committee already knows, Ivanka did not speak at the January 6 rally. As she publicly stated that day at 3:15 p.m., "any security breach or disrespect to our law enforcement is unacceptable. The violence must stop immediately. Please be peaceful.'"

The letter is the committee's latest attempt to seek information from inside the Trump family as it has broadened its investigation. Earlier this week, it issued subpoenas to Rudy Giuliani and other members of Trump's legal team who filed bogus legal challenges to the 2020 election that fueled the lie that race had been stolen from the former president.

On Wednesday evening the Supreme Court rejected a bid by Mr Trump to block the release of White House records sought by the committee, clearing the way for their release.

The National Archives began to turn over the hundreds of pages of records to the nine-member panel almost immediately. They include presidential diaries, visitor logs, speech drafts and handwritten notes dealing with January 6 from the files of former chief of staff Mark Meadows.

The panel says it has interviewed nearly 400 people and issued dozens of subpoenas as it prepares a report set for release before the November midterm elections.

The committee says the extraordinary trove of material it has collected - 35,000 pages of records so far, including texts, emails and phone records from people close to Mr Trump is fleshing out critical details of the worst attack on the Capitol in two centuries, which played out on live television.

The next phase of the investigation will be more public-facing, starting with a series of public hearings in the coming months.

Separately, a prosecutor investigating possible attempts by Mr Trump to interfere in the 2020 general election in Georgia called for a special grand jury to help move the case along.

During a phone call on January 2, Mr Trump urged Georgia Secretary of State Brad Raffensperger to "find" enough votes to overturn his loss in the state to Joe Biden. The transcript quotes Mr Trump telling Mr Raffensperger: "I just want to find 11,780 votes," which is the number he needed to win Georgia. He has denied wrongdoing.
